Metso Chain Seized – Pins Won’t Move, Line Down
Seized pins are blocking restart on your Metso chain-driven equipment right now.
Why Pins Seize or Stick
Your line is down, production stalled, and the chain pins refuse to budge.
Corrosion, wear, and contamination lock them solid under heavy load.
Torch risks add danger while every hour costs thousands.
Why This Happens
Chain pins seize when corrosion builds up, wear widens clearances then packs with debris, and repeated load cycling plus thermal effects bind them tight.
The result: pins that won’t press out with standard tools, halting operations instantly.
Downtime drags on until the seizure is broken safely and quickly.
